Greg gave her all she would take. The old flivver roared and rocked down the Drive, and the few pedestrians homeward bound stopped and stared at the phenomenon. Most of the motor traffic was bound in the opposite direction, and on his side of the road Greg had a clear passage. The bright round globes flashed past, the cars they passed seemed to be standing still. Greg prayed that his old tires would support the strain. The flivver had long ago seen her best days, and like an old horse she was scarcely making the speed that the violence of her action would indicate. Thirty miles was about her limit. Through the little window in the back Amy kept watch on their pursuers. "They're gaining on us!" she said despairingly. And indeed the bigger car drew up on them with ease, once they let her out. De Socotra was leaning far out of the window urging the driver on. The policeman rode in front. Foot-passengers becoming infected with the excitement of the chase started to run after, but were soon out-distanced. Motor cars bound up-town slowed down, turned and joined in the chase. The pursuing car little by little drew abreast on the outside of the flivver. The driver pinched Greg into the curb as close as he dared, hoping to force him to stop. No more than a foot separated the running-boards of the two flying vehicles. Amy shrank back into the darkest corner. The water was now boiling furiously out of the radiator of the flivver, and Greg knew she must soon begin to miss and slacken speed. But he held her to it. The second car was now running wheel to wheel with Greg's, and the policeman leaning out was almost able to put a hand on his shoulder. "Stop, you!" he commanded. At that moment Greg saw an opening, and he obeyed the order quicker than they looked for. Throwing out his clutch and applying brakes, he let the other car shoot ahead. Turning out behind it, he darted up a side street. Their pursuers carried on a hundred feet or more had to turn around in the Drive and come back. Cars bound up-town got in their way. Greg might have succeeded in giving them the slip altogether had it not been for the other cars which had taken up the chase out of sheer excitement. These cars were far enough in the rear to follow Greg directly into the side street and to point the way to the policeman when he came up. Greg twisted and turned to the best of his ability; off the Drive the streets were deserted; into West End Avenue, into another side street, into the Drive again. A whole string of cars was stretched out behind him now. Rarely had the sporty chauffeurs such a chance to defy the speed laws. It was like pandemonium sweeping through those astonished quiet streets. The little flivver was like a mangy fox pursued by a pack of sleek hounds.
